1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station, a radio resource control (RRC) message including configuration information for monitoring power saving information;
in case that a long discontinuous reception (DRX) cycle is used and a subframe where the long DRX cycle starts is determined, identifying whether power saving information monitoring is configured;
in case that the power saving information monitoring is configured, monitoring a physical downlink control channel (PDDCH) for detection of the power saving information, based on the configuration information; and
in case that the power saving information is not detected, starting a drx-onDurationTimer.
